Microsoft today announced a tighter integration between Teams and Yammer. Teams users can now add a Yammer tab to their Teams channel that loads a specified group or topic feed from Yammer. This will allow users to follow and share conversations in Yammer without having to leave Teams app. A subscription to Yammer Enterprise is required in order to be able to add this tab. Whenever a Teams user visits Yammer tab, user will be authenticated again by Yammer, so that user can only see Yammer content based on permissions.
This new Yammer tab feature in Teams is only available on the web and desktop.
